Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
SAE 30304 (SAE J405) and ASTM A959 .- (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
SAE 30304 is typically used for used for chemical equipment, food processing machinery, architectural panels, fasteners, pressure vessels, and heat exchangers., while ASTM A959 .- is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
SAE 30304 is defined under SAE International, originating from United States, while ASTM A959 .- is defined under ASTM International, originating from United States.
As per chemical composition, SAE 30304 vs ASTM A959 .- is a 74.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
